HelloPharmacist Scorecard of Wintergreen Herb by TerraVita

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: wintergreen herb glycerite liquid extract. It's designed as a liquid form, which makes it easy to measure and take by mouth.

The extract is prepared in glycerin, an inert inactive ingredient that serves as the base.

Does it work?

Couldn't assess
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

This is a single-ingredient Wintergreen product and its label doesn't state a use — see Wintergreen's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence for wintergreen isn't established in our data. We don't have reliable evidence to rate whether it works for back pain, muscle soreness, or joint pain.

The evidence, ingredient by ingredient Wintergreen

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Here's where you need to be careful: wintergreen oil is extremely toxic if swallowed, so oral use—including this liquid—carries real risk. Orally, wintergreen oil can cause salicylate poisoning, with symptoms like headache, ringing in the ears, and confusion.

The product label advises avoiding this during pregnancy due to salicylate exposure and insufficient safety data, and it's likely unsafe during breastfeeding. Topically, wintergreen oil itself seems to be well tolerated, but don't cover it with an occlusive dressing (like a bandage), because that increases absorption of toxic amounts of methyl salicylate and can cause contact dermatitis (an itchy, inflamed skin reaction).

Topical analgesic gels, lotions, creams, ointments, liniments, and sprays can contain up to 55% methyl salicylate.

Likelihood Probable Evidence D
Aspirin

Using wintergreen oil topically in large amounts, with occlusive dressings, or for prolonged periods of time might increase the risk of additive salicylate toxicity when used with aspirin.

Wintergreen Herb by TerraVita: Common Questions

Does Wintergreen Herb by TerraVita interact with any medications?
Yes. Based on its ingredients, Wintergreen Herb has a known interaction with 37 medications, including 2 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Wintergreen Herb contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Is wintergreen safe to swallow?
No—wintergreen oil is extremely toxic if swallowed. The product label advises against oral use. Swallowing it can cause salicylate poisoning, with symptoms like headache, ringing in your ears, and confusion.
Can I use this if I take warfarin?
You should not use this without talking to your pharmacist first. Wintergreen contains methyl salicylate, which can be absorbed into your bloodstream and increase warfarin's effects, raising your bleeding risk. Case reports document this problem.
What about using it topically—is that safer?
Topically, wintergreen oil itself is generally well tolerated, but don't cover the area with a bandage or occlusive dressing. That increases how much of the oil gets absorbed into your body and can cause toxic effects or contact dermatitis.
Is it safe during pregnancy or breastfeeding?
The product label advises against it during pregnancy due to salicylate exposure and lack of safety data. It's rated likely unsafe during breastfeeding. Talk to your doctor or pharmacist for personalized guidance.
Does wintergreen actually work for back pain or sore muscles?
We don't have reliable evidence in our data to say whether it works for back pain, muscle soreness, or joint pain.
